I recently found out something that may explain all the mikes and booms spotted in videos now. Apparently the movies are filmed in a wider format than is shown even on the big screen and the movie company is so used to the cinemas cropping the tops and sides to proper size that they aren't as careful as they used to be. This still makes it a mistake in my book, but it explains why they are as sloppy as they are. The site I read this on is www.straightdope.com Do a search to find whatever it is you want to know. A really interesting place.
